Typically, when I travel outside of my city (Costa Mesa/Newport Beach), I will get a sinus headache that lasts for about 6 hours. This has happened at work (I work about 35 miles away in an agricultural area) and I have had to leave work because no amount of Advil will alleviate the headache. Since taking this product though, I haven't experienced these types of headaches. I recently went to Italy for two weeks and even though I spent a few days in the city and most days outside in the wind, I was not bothered by the city pollution and other allergens. Again, before this product I would usually get a headache from the bus exhaust or from being a park on a windy day. With the Sinus and Seasonal capsules, I don't experience any of my previous symptoms. As far as dosage, I can take one capsule every other day most of the time and not experience more than a few sneezes in the morning. If I feel like I will be outside all day and there might be people smoking cigarettes, then I will take an extra pill a few hours after the first one. It seems like cigarettes, strong perfume, or chemicals like bleach will trigger an instant headache for me, but this product helps if I take one more pill than my usual before being exposed. So, I carry an extra pill in my purse just in case. For instance, I was on an airplane (12 hour flight) and before I knew it the bathrooms were being cleaned with the strongest smelling chemicals! It was floral scented which was nice, but it was so strong that it triggered a headache within a few minutes. I took my extra pill and applied some white flower (oil) and my headache subsided after about 20 minutes. If I didn't have the extra pill, the headache would have likely lasted about six hours. I'm sure if I took the pill daily, then I would not need to carry an extra one, but since these encounters do not happen too often, I would rather only take what my body needs. I have been taking this product for about three months now and feel the results are the best of all of the products I have tried over the last several years (D-Hist, Generic Loratadine, Rootology). I know how suffering from allergies can dictate one's daily activities (perhaps even one's general happiness) and I think I have found complete relief by using this product. I hope this review helps others! Update (March 2017): I am still using this product and still experience allergy relief to the same degree. I have been recommending it to others well. Review: Hot diggity! .... in other words - it actually works - I am plagued with Chronic Sinusitis and much like the chicken and the egg - I have no earthly idea what started where. I have Eosinophilic Asthma and a smattering of allergies, near constant post nasal drip and clearing my throat, sinus congestion, endless bouts of coughing attacks appearing out of nowhere, and sinus pain. Sleep is the only solution I have found to give the reactivity of my respiratory system a break. As soon as I drink, or eat anything - including plain water, the entire ordeal starts all over again. I regularly see a pulmonologist, allergist, ENT and gastroenterologist. None can measurably alleviate my respiratory symptoms and PND. Because I live in Colorado with its extremely dry climate, I faithfully use a humidifier and nasal irrigation. Those are the remedies my medical specialists offer the most. As I am apt to do, I searched desertcart for those issues I was hoping to improve. Of everything I stumbled across, the reviews for "LES Labs Sinus & Seasonal, Natural Supplement for Sinus & Nasal Health" were almost too good to be true. Many voiced skepticism about the efficacy of this product. I too was highly skeptical. I bit the bullet and ordered a bottle, although I thought it was awfully expensive. Once received, I waited for a day that was highly problematic - after all, I wanted to give it a real test. I took one capsule. I had low expectations while hoping, but not anticipating, some sort of symptom improvement. I busied myself with a few minor tasks and no later than 5 minutes after taking the "LES Labs Sinus & Seasonal, Natural Supplement for Sinus & Nasal Health" realized there WAS a drastic difference. I'm not easily prone to suggestion and thought I must have psyched myself up too much. The next morning, I still had symptoms that were relieved. I remained unwilling to believe it was THAT easy to alleviate my most bothersome symptoms after all the nonsense I have been through. I waited another week and tried it again. Unbelievably, the difference was clearly obvious within the first few minutes. I've never had such an immediate beneficial reaction to a supplemental formula. I've since shared it with friends with similar sinus concerns and their experiences matched mine. So, if you read the reviews and thought "yeah sure", I felt the same. I'm still surprised it works so well. If it wasn't otherwise obvious, I was not compensated in ANY way for my review. (Actually, in more than 20 years as an desertcart customer, I've never been approached or offered anything in exchange for a review.) ## Features - Nasal health minus the drowsiness: Our Non GMO and drug-free formula helps promote sinus & nasal health while supporting lung & respiratory function.

Our butterbur is carefully processed to ensure purity and safety. **Q: Can Sinus & Seasonal Support be used daily?** A: Yes, this formula is designed for daily use to help manage seasonal changes and maintain long-term sinus health. It is particularly beneficial for individuals sensitive to pollen, dust, and other environmental triggers. **Q: How soon can results be expected?** A: Many users report improved sinus clarity, reduced nasal congestion, and better overall comfort within a few days of consistent use. For optimal results, it is best to take Sinus & Seasonal Support before peak allergy season. **Q: Is this supplement safe for long-term use?** A: Yes, all ingredients are naturally derived and non-drowsy, making this a safe and effective alternative to traditional seasonal relief medications. **Q: Does this product help with non-seasonal sinus issues?** A: Yes! While designed for seasonal allergies, its anti-inflammatory and mucus-clearing properties can also support year-round sinus health for those sensitive to dust, pet dander, and environmental pollutants. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This Product Brought Me Complete Allergy Relief *by S***F on July 12, 2016* I have tried several other products with overlapping ingredients, but there were always side effects and the products were most effective if I took more than one capsule a day.

My story: I spent YEARS trying to find some way to deal with spring, summer and fall allergies. My symptoms change, sometimes it's sinusitis, sometimes watery eyes, always a feeling of misery, fatigue, light fever, depression-like lethargy in the morning and early afternoon when my histamines are sucking the life out of me. All the usual things help a little and should not be discounted: I shower EVERY time I come inside, use saline solution twice a day, windows closed from March to November and air conditioning on on the most beautiful breezy days of the year (I waited 20 years to get an affordable apartment in Manhattan with cross-ventilation for this!) I have never been diagnosed and when I tell the doctor my symptoms he tells me how bad other people's are compared to mine and gives me my options -- antihistamines, nasal steroids, all the things that make me feel worse or do nothing. No one has researched allergies and what brings them on more than I have, and I came across these natural antihistamines in my travels and specifically this brand. Good news: last year, I had a virtually allergy-free year (including indoor stuff like dust-related reactions) and couldn't stop talking about it. Most people were constantly complaining about how bad a year it was. Can't tell you how wonderful it was from March to early August. Bad news: Then bang, fall allergies hit me like a ton of bricks. Long story short, I'm pretty sure that butterbur is great AT FIRST for tree and grass, even some dust, allergies, but not for ragweed and may even make it worse. I stopped taking these supplements until the end of the year and now I'm back on them, but not getting any great effect. Miserable all the time, except for one thing. They seem to give a small amount of relief during my worst moments (around 11 am when I feel like I'm about to die) and really help me cope. I would recommend taking one in the morning as early as possible and then another if it's a bad day as a treatment. Maybe also a stinging nettle root capsule in addition in between. I do realize that allergies are a medical mystery to some extent, so I am patient. I give this product 4 stars by default since nothing else works ever. ## Frequently Bought Together - LES Labs Sinus & Seasonal – Sinus Relief, Nasal Health, Balanced Histamine Response, Clear Lungs & Respiratory Health – Butterbur, Quercetin, Nettle Root & Bromelain – Non-GMO Supplement – 60 Capsules - LES Labs Inflammatory Health – Joint Support, Muscle Function & Relaxation, Mobility– Turmeric, Boswellia, Quercetin, Ginger & CoQ10 – Non-GMO Supplement – 60 Capsules - LES Labs Cortisol Health – Stress Relief, Balanced Cortisol Response, Relaxation & Deep Sleep – Phosphatidylserine, Magnesium, Magnolia Bark, Rhodiola Rosea & Ashwagandha – Non-GMO – 60 Capsules --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/2371821-les-labs-sinus-and-seasonal-supplement-for-respiratory-support-60](https://www.desertcart.co.za/products/2371821-les-labs-sinus-and-seasonal-supplement-for-respiratory-support-60) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-03*
